Help with zip 100

hi guys, I recently bought a zip 50 and the engine gave up on me. I bought a second hand 100cc engine and bolted it in. I bought a 100cc cdi aswell and it came with a carb.

The bike runs but bogs down and runs as slow as a 50 would. I'm using the airbox from the original 50 because I think they ar the same?

I'm also using the exhaust from the 50 for the same reason. Could the 50 exhaust be restricting the 100 engine? I've tried running it without the exhaust to test but it just bogs down big time. I've also tried putting more air into the airbox but still no luck.

Any help or thoughts will be greatly appreciated.


Thanks

 

Agree with him^^
Can't be doing that.

 

I'm confused can you clear this up. the engine fits perfectly into the 50 frame it's only a touch longer at the back and shows no difference at all really.

so is the exhaust and airbox different from the 50 to the 100. I didn't think it would make a difference as the exhaust is designed restricted anyway (washer taken out) and I can put some holes in the 50 airbox to add more air.

 

the exhaust is de restricted I mean

 

can't do what?

 

see what you mean although the 50 exhaust is a 100 one with a restrictions in the top? and I've taken the restrictor out?

and I can drill holes for more air flow can't I?

everything else is 100cc as I changed the cdi. spark plug and coil etc.

I'm considering buying a 100 airbox and exhaust to see if they are the same but don't want to waste my money.

thanks for your help though it's appropriated.

 

thanks. yeh I'll do that it's a wicked bike small and light so with the 100 engine should be great.

cheers

 

hi guys I need more help. the new exhaust and airbox has helped the engine runs much better I now need to know where a couple of hoses go.

the first is on the valve cover it's a hose and I'm not sure where it goes to. I'm thinking it goes to the airbox as there is a spot for a hose but not sure.

the second hose is the secondary airbox. it's got the main big hose but there is a spot for another hose?

and the second little pipe for the airbox.

 

hose to somewhere

 

valve cover hose to somewhere

 

hose from airbox to somewhere

 

The 3rd pic is for a small tube not sure what it goes to I think the valve cover tube goes to the airbox one?

I need to check the reed valve because one hose is already connected to it this is a second smaller hose coming from the sas.

Thanks for your help I will take more pics can tomorrow which might help.

 

I've got it running today but it's only hitting 25 to 30 MPH. I've set the valves correctly and carb has been cleaned but it's driving me mad. the 100 should do 45 to 50 easy but it struggled to do 30.

 

Can anyone tell me where hose 9 connects to, the pic dosnt show.


Also how the sas can be removed?
